Paper Towel Rainbow - 4 Year Old Class

In class we put coloured water into three mason jars, and added the primary colours, red, blue and yellow.

We then placed the jars in a circle with three empty jars in-between, and had paper towel rolling from one jar to the next. The children were very interested in this science experiment and what the outcome would be.

The process took a few days, but the children were able to see the colours absorb into the towels, creating green, orange and purple.

 


We followed up with an interactive activity allowing children to mix the primary colours using vinegar with food colouring, droppers, and trays filled with baking soda.







 
The activity was much enjoyed by the children, and the effect quite beautiful.

Some comments:

Matias – It looks like it's steaming!

Kaius – It's bubbling!

Lucas – It's like a colourful volcano!

Alara – It's like cooking with ginger!
 

Until next time :)

MWF 4 Hour Class When I’m writing a documentation, one of the hardest things for me is to decide what pictures, stories and reflections I’ll share with you. There are so many joyful, meaningful moments and every day’s learning experiences!

Some of the benefit of connecting children with nature include: supporting creativity and problem solving, increasing physical activity, reducing stress, promoting social emotional development. We see children as innate scientists, artists, builders… full of wonders and curiosity they can nourish and experiment while they are playing in nature.

3 and 4 Year Old Classes – Holiday Time

The preschool 3 and 4 year old morning classes have been busy preparing for the holidays over the past few weeks. Along with many other activities, each child has made a gift for their families. These gifts are now wrapped and ready to be sent home, and we are sure they will be well received! We also showed the children our Preschool Donation Box and spoke about the importance of giving to those who are less fortunate than us. We have decorated a Christmas tree and created two very large snowman (which will be on display at the family potluck!) It was fun to stand back and watch the children strategize and work together as a team. The preschoolers have also been practising the songs they will sing at the family potluck and for the Hugh Boyd Seniors. In the coming week they will be decorating a gingerbread cookie with their big buddy - this always makes for a fun day! Inspirational Paintings     ...
